Excitation of bridges to test dynamic properties

Have you ever heard of the tragic collapse of Tacoma Narrows Bridge in 1940 which was later called the “Pearl Harbor of engineering“? Unfortunately, the structure of the bridge had not been tested the way our APS shakers can test its dynamic properties.

Further Applications for ELECTRO-SEIS® Long Stroke Shakers

International leaders in research on vibration serviceability and its application to real world problems, such as Vibration Engineering Section (VES) have used our products for nearly two decades successfully. The APS Dynamics shakers with ball bearings were used testing civil structures such as concrete floors or footbridges in open space conditions.

VES - formerly from the Department of Civil and Structural Engineering at the University of Sheffield - have recently moved to the University of Exeter where they continue their research and consultancy.
